Application filed August 9, 1926. SerialNo. 128,062.

This invention relates to means for mounting and adjusting the workerand stripper rolls of a carding machine in proper relation to the cardcylinder.

In this type of carding machine, well known and familiar to one skilledin this art, the card cylinder is partially surrounded by a plurality ofunits each comprising a worker roll and a stripper roll. The number ofthese units varies and it is frequently desirable to be able to-changethe number of units employed on a given machine.

One object of the present invention is to provide a simple and efficientmeans whereby, either in'the assembling of themachine or as requiredinthe subsequent use of the machine, any required number of worker andstripper roll units may readily be mounted in the machine. l

A further object of theinvention-is to provide apair of bearing unitsfor each worker and stripper roll unit together with means for securingeach such bearing unit in circumferentially adjustable position on thecorresponding side arch of the carding machine, thus enabling anyrequired number of worker and stripper roll units to be employed. a

These and other objects and features of the invention will appear morefully from the accompanying description and drawings and will beparticularly pointed outin the claims. 7

The drawings illustrate so much of an ordinary type of carding machineas is necessary to a disclosure of the present invention together with apreferred form of construction embodying the said invention.

In the drawings V I Fig. 1 is a side elevation, chiefly diagrammatic, ofthe carding machine.

Fig. 2 is a view in side elevation of a section of one of the sidearches illustrating one bearing unit for one unit of worker and stripperrolls embodying the invention.

Fig. 3 is a view-in cross section taken on the line 33 of Fig. 2. I

Fig. 4 is a view in cross section taken on the line 44: of Fig. 2. I

Fig. 5 is a view in cross section taken 'on theline 5-5 of-Fig. 2. a

An ordinary type of carding machine is shown diagrammatically in Fig. 1having at.

each'side a side, frame 1 supporting a side arch 2. The main cardcylinder 3 is journalled on an axis 4 in theside arches. This cylinderis partially. surrounded by a plurality of worker and stripper rollunits, the worker rolls being indicated. at 5 and "the' stripper rollsat The outer peripheral face of each side arch 1s preferably ground orfinished off to present a plurality of fiat faced concentric ribs'7.Between two of these ribs a. T shaped slot 8 is formed extending alsoconcentrically of the side arch.

As the construction of the worker and stripper roll journals, thebearing units therefor and the means for adjustably mounting-the bearingunits and foradjust ing the respective journal bearings is preferablythe same on both sides of the machine and the same for each unit, it isonly necessary toillustrate and describe the construction for one unit.

Each bearing unit is shown as comprising a somewhat trapezoidal shapedbase I plate 9 adapted to'seat against the faces of the ribs 7, andpreferably provided with a flange 10 overlying the periphery of the sidearch. This base plate is provided with one or more bolts, herein shownas two by means of which it-is securedin circumferentially adjustableposition to the side arch. In the construction illustrated these bolts11 have their heads 12 seated in the T shaped slot 8 and their stemspassing through the base plate an dtheir threadedends provided with thenuts 13. Thus it will be seen that each base plate is readily positionedand locked or securedinadjusted position of any desired pointcircumferentially of the side arch. While the T-shaped slot is disclosedas extending throughout the face of the arch,

the important feature is that it extends throughout the entire segmentof the arch face where the worker and stripper rolls are positioned.Thus in assembling the machine any desired number of worker roll andstripper roll units may be provided and furthermore the number of suchunits may required by readily be changed whenever This standany givenset of conditions.

ardizes the side arch construction and the.

construction of the units thus economizing in the manufacture of themachines. Thls also gives great flexibility tothe machine in the handsof the user enabling it to meet varying conditions of use.

In the preferred construction illustrated the base plate 9 at one sideis provided with parallel ribs M-eXtending parallel to a radius of theside arch. These ribs constitute a guide way. A bearing block 15,recessed from its inner surface at 16 is mounted to slide, on the guideway formed by the ribs 14, radially of the arch. This bearing block atits upper end, carries the journal. bearing for a worker roll 5. Asillustrated'the hearing block,- fo .,tl1is purpose, is formed. into asemi-circular seat 17 in which rests the journal sleeve 18 in which inturn is mounted the journal 19 of the workerroll. Beneath the bearingblock a lug20 projects integrally from the base plate 9. A screw 21passes through the aperture iuthis lug and is threaded into the bearingbloclrand is provided with nuts 22 above and below the lugs20. It willthus be seen that by turning the nuts 22 the bearing block may he slidradially on the guide wayl thus to adjust the journal bearing of theworker roll accurately toward and from the card cylinder but withoutchanging its position cireunrl'erentially of the card cylinder and arch.

A bolt 23 isalso provided at the upper end of the: base plate passingthrough a radial slot 2a in the bearing block 15 and provided at itsouter end with a washer 25,. and a nut 26. Thisbolt, as well as the twonuts 22 provide means for locking the bearing block firmly in itsadjusted position.

A second bearing block 01' generally similar construction. tothatalready described is provided for the journal bearing 28 of thejournal 29 of the stripper roll 6. This bearing-block is seated, uponflat ribs 30. on the base plate. Beneath this bearing block the baseplate is provided with anotherintegrally projecting lug 31 and a screw32. passes through an aperture in this lug, and is threaded into thelower end of the bearing block 27 and is provided with nuts 33above andbelow the lug. Thus it will be seen that the bearing block 27 is alsoadjustable, by a similar means to that already described in aradialdirections.

Near its upper edge the base plate 9 is provided with a projecting lug34 centrally of the ribs 30. Screws 35 are threaded through the sidewalls of the bearing block 27 and; abut thislug 34-. Consequently byadjusting these set. screws the upper end of the. bearing block .27 maybe adjusted ,circumt'erentiallyot theareh. This adjustment iscomparatively slight andmay readily be made by looseningithe nuts 33slightly. This bearing block is also locked in adjusted position notonly by theset screws 35 andthe nuts 33 but by a bolt 36 passing throughthe base plate and passing through an opening 3? inthe bearing block andhaving at the face 01"- the bearing block a washer 38 and nut 39.

It will be seen that the bearing block for the stripper roll journal isadjustedboth radially and circumi erentially on the base plate and isreadily locked in any adjusted position.

When therefore, after the grinding of the worker and stripper rolls, itbecomes necessary to readjust the positioiiot these rolls to correct forthe grinding operation, it willbe seen then that the adjustment providedfor the bearing block and theworker roll insures that the axis of theworker roll will alwaysremain in the plane: of theaxisof the cardcylinder while the distance between the surfaces oi the worker roll andcard cylinder-will be accurately .determinedby this adjustn'ient, whilethe adjustment provided tor the stripper roll enables each journal ofthe stripper roll to be adjustedtoward and from either orboth of thesurfaces of the card cylinderand workerroll to piace the stripper rollin the required cooperative relation withboth.

Having thus described the invention, what by Letters Patent, is:

LA carding machine comprisinga frame having side arches, a card cylinderjournalled in the frame between the arches, a plurality of roll unitsco-operating with the cylinder in the ca-rdingoperation and each isclaimed as new, and desired to be secured loo comprising a worker rolland a stripperroll,

plate radially of the arch and; a journal bearing for the stripper-rolladjustable on the base plate radially and circumferentially of the arch.l

2. A carding machine comp-rising a frame having side arches a cardcylinder .journalled in the frame; between the ,arches, a y

plurality of roll units cooperating with the cylinder in the cardingoperation and each comprising a worker roll and stripper-roll, a pair ofbearing units toreach 'roll'unit, each bearing unit comprising a baseplate seated against the corresponding sidearch face, each side archhaving a circumferential way on its face in the formof a: T shapedgroove extending continuously around the arch concentric With the axisof the card cylinder, and a bolt passing through each base plate Withits head located in the corresponding T shaped groove for rigidlysecuring the base plate seated against the side arch at any desiredcircumferential position, each bearing unit comprising a journal hearingfor the Worker roll adjustable on the base plate radially of the archand a journal bearing for the stripper roll adjust- 10 able on the baseplate radially and circumferentially of the arch.

In testimony whereof, I have signedmy name to this specification.
